ELECTRIC-LA1VIP SOCKET-COVER AND SHADE-HOLDER.

Specification of Letters Patent.

Patented June 21, 1910.

Applica filed February 16, 1910. Serial No. 544,190.

To all whom it may concern:

Be it known that I, GEORGE W. CAssmY, a citizen of the United States,residing at East Orange, in the county of Essex and State of New Jersey,have invented a new and useful Improvement in Electric-LampSocket-Covers and Shade-Holders, of which the following is aspecification.

The object I have in view is to produce an electric lamp socket coverand shade holder which will effectively perform its function of coveringthe socket and supporting the shade, will give access for the readyremoval of the socket, and will be of such construction that it will becheap to make and will lend itself to an ornamental design.

In the accompanying drawing, Figure 1 is an elevation of my improvedsocket cover and shade holder, showing the fixture nipple to which it isattached, and the shade supported thereby; and Fig. 2 is a verticalsection of the same parts, showing the fixture nipple and the lampsocket in elevation.

The socket cover and shade holder has a top 3 which may be of domeshape, and having at its lower edge an external screw thread 4: abovewhich is a shoulder 5. The top 3 is made in one piece with a dependingcentral sleeve 6 which is internally screw threaded. The fixture nipple7 is provided with a long screw threaded extension 8, upon which thesleeve 6, which is internally screw threaded, is mounted. The extension8 of the nipple passes through the sleeve 6 and receives upon its lowerend the electric lamp socket 9, which is held thereon by engaging screwthreads and by set screw 10. The screw threaded collar 11 on the end ofthe lamp socket screws on the extension 8 until it seats firmly againstthe lower end of the sleeve 6,loosening of the socket being prevented bythe set screw 10. Below the top 3 is a depending cylindrical shell 12which extends downwardly on slightly flaring lines and then flaresoutwardly to form a shoulder 13, against which is seated the lip of theshade 14. Below the shoulder 13 the shell is formed to provide a band 15which is approximately vertical or parallel to the axis of the device,and in the band 15 are the set screws 16 for engaging the lip of theshade. Below the band 15 the shell again curves outwardly to form ashoulder 17 and then curves inwardly to a finished ed e 18, which asnearly as practicable makes contact with the sides of the shade 14 so asto steady the shade and prevent it from wabbling. The finished edge 18is approximately on a level with the lower end of the lamp socket.

Inside of the bearing of the lip of the shade upon the shoulder 13, theshell is provided with ventilating openings 19, which afford ventilationfor the heated air arising from the electric lamp. The shell 12 is screwthreaded at its upper end and engages with the screw threads 4: of thetop 3 so that the socket cover and shade holder can be divided at thispoint by unscrewing the shell 12 and withdrawing it downwardly, thusgiving access to the set screw 10 of the socket and enabling the socketto be removed without removing the top 3 from the fixture, and alsowithout removing the socket enabling the socket shell to be removed togive access to the wiring.

What I claim is:

1. An electric lamp socket cover and shade holder wherein are combined atop adapted to be secured to the fixture and to receive a lamp socketcentrally therein, a depending shell covering the socket and removablysecured to the top, the joint being located so as to give access to thesocket holding devices, substantially as set forth.

2. An electric lamp socket cover and shade holder, wherein are combineda top 3 having a centrally depending sleeve 6 and a shell 12 adapted tocover the socket, and removably secured to the top so as to give accessto the socket holding set screw, substantially as set forth.

3. An electric lamp socket cover and shade holder, comprising adepending shell provided with a shoulder 13 for seating the lip of theshade, an approximately vertical band 15 below the shoulder 13 forcarrying the set screws 16 and an inwardly extending lower end tosupport the sides of the shade below the set screws, substantially asset forth.

4. An electric lamp socket cover and shade holder wherein are combined atop 3 having a centrally depending sleeve 6 and a screw threaded lowerend, a shell 12 screw threaded to the top and provided with a shoulder13 and approximately vertical band 15 and an inwardly turned lower edgeand the set screws 16 passing through the band 15, substantially as setforth.
